' ,I WATER-FEEDER FOR BolLERs.

srncrrlcArIoN forming part of Letters Patent No. 686,528, dated November 12, i901.

Application led June l, 1901.

To all whom t may concern:

Be it known that I, SAMUEL D. Morir, of Passaic, Passaic county, New Jersey, have invented certain new and useful Improvements in VVater-Feeders for Boilers, of which the following is a full,- clear, and exact description;

My invention. relates to improvements in water-feeds such as are used for supplying water to steam-boilers; and the object of my invention is to produce a very simple and economical device which can be applied to an ordinary boiler near the water-line and which can be operated mechanically so as to feed the water into the boiler by gravity as fast as it is needed and no faster.

Another object of my invention is to produce a device of this character which is particularly adapted for automobile-work, and which will run faster or slower as the mechanism of the vehicle moves faster or slower, thus accommodating the feed to the steam consumption.

With these ends in View my invention consists of certain features of construction and combinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar figures of reference refer to similar parts throughout the several views.'

Figure 1 is a-vertical cross-section of my improved waterfeed,showing the applicationl of the same vto a boiler. Fig. 2 is a broken vertical longitudinal section at right angles to the view shown in Fig. 1. Fig. 3 is a detail side elevation of the valve controlling the steam and water inlets; and Fig. 4 is a sectional plan of the lower valve, which controls the iiow of water to the boiler.

In carrying out my invention I employ a receptacle 18,Which has a suitable water-inlet 19 located near the top, and the receptacle is of a size to hold a convenient charge of water for the boiler, the size of course varying with the size of the boiler. This receptacle is preferably of a generally cylindrical shape, although not necessarily so, and it has connections 20 and 22 at top and bottom leading to the boiler 21. The boiler of course may be of any usual construction.

Arranged vertically in the receptacle 18 is a valve stem or shaft 37, which is provided sena No. 62,811. (No man.)

1 at the upper end withva valve 38 and at the lower end with 'a valve 38a, these valves being circular in cross-section and turning in suitable boxes or bearings 38b and 38", which are formed, preferably, integral with the receptacle 18. It will be understood that the inlet 19 for water and the inlet for steam are both opposite the valve 38, and sothis is made to control both the steam and the waterA supply, and to this end it has a port 39 40, the part 39 leading vupward intov the valve from the under side thereof and the part 40 extending horizontally through the valve, so that it may register with the water-inlet 19 and the steam-inletr20 as the valve 38 is revolved. The lower valve 38a has a similar port except that the part 39 extends upward into the receptacle instead of downward, while the part 40 of the port is adapted to register with the connection 22, so that water can flow from the receptacle 18 through the port 39 40 of the lower valve into the boiler.

It will be seen that as the valve-stem 37 is rotated the boiler connections will be alternately opened and closed and that a similar action takes place with the Water-inlet 19, so that when the valves are turned to open the water-inlet the boiler connections are closed and the water flows freely into the receptacle 18; but the continued movement of the valves closesl the water connection and opens the boiler connections 20 22, so that steam-pressure enters through the connection 20, causing the Water to .ow from the receptacle 18 through the connection 22 into the boiler. If the water-level in theboiler is above the connection 20, then of course no feeding will take place; but as kit lowers the feeding is accomplished and just the requisite supply is furnished.

It will be noticed that in cool weather especially the steam in the receptacle 18 will condense rapidly, and if it is desired condensation may be hastened by jacketing the receptacle, and when this condensation occurs a partial vacuum is created, so that water flows very quickly into the receptacle when the valve is opened to the inlet 19. In fact, it will iiow even though the water-supply be at a slightly-lower level than the receptacle 18.

Obviously many ordinary mechanical devices can be employed to turn the valve-stem 37; but I have illustrated a simple means in which the valve-stem is provided with a beveled pinion 4l, meshing with a beveled pinion 42 on the shaft 45, which extends outward through a stuffing-box 44 in one end of the receptacle 18, while the inner end of the shaft 45 is supported on a suitable bracket 43. The shaft 45 can be turned by any suitable connection with some running part of the machinery driven by steam supply from the boiler` 2l, and if it is a running part of an automobile it is of course evident that the shaft will be driven faster or slower, according as the vehicle goes faster or slower, and thus the water-feed will be timed to correspond to the steam consumption. Where a relatively constant speed is maintained, it follows that a relatively constant watersupply is desirable, so that the water-feed illustrated is adapted to any ordinary service.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is

1. A device of the kind described, comprising a stationary receptacle having a waterinlet and boiler connection near the top and a boiler connection near the bottom, a ported valve within the receptacle turning opposite the upper boiler connection and water-inlet so as to alternately open the said connection and inlet to the receptacle, a ported valve within the receptacle turning opposite the lower boiler connection so as to connect it with the receptacle, and means for simnltaneously turning the two valves.

2. As an improved article of manufacture,

a water-feed comprising a stationary receptacle having boiler connections near the top and bottom and a water-inlet near the top, and a pair of rotary valves mounted within the receptacle on a single stem and turning opposite the connections and water-inlet so as to alternately open and close the boiler connections and water-inlet.

3. The combination with astationary receptacle having a water-inlet and a boiler connection near the top and a boiler connection near the bottom, of valve-bearings within the receptacle opposite the said connections and water-inlet, rotary valves journaled in the said bearings and adapted to alternately open and close the boiler connections and wat-erinlet, a single stem carrying the two valves, and means for turning the stem.

4. The combination with astationary receptacle having boiler connections at top and bottom and a water-inlet near the top, of a pair of rotary valves journaled within the receptacle opposite the connections and water-inlet and adapted to alternately open and close the said connections and water-inlet, a rotary shaft extending outward through the receptacle, and an operative connection between the shaft and the valves whereby the motion of the shaft is communicated to the valves.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
